Manuscript Summary: This parchment manuscript written about the end of the 15th century, with musical notation and book decoration, contains the Proprium de tempore (Winter portion, First Sunday of Advent through Good Friday). The text breaks off at the bottom of a page in the Good Friday antiphon, at the end of the third Psalm for Lauds. The antiphonary was held by the St. Gall Dominican convent of St. Katharina, where it may also have been written. The same hand also wrote the convent's manuscript containing the summer portion of the antiphonary (Wil, Dominikanerinnenkloster St. Katharina, M III). (fas)
